Aortic root abscess is a complication of aortic valve endocarditis that is associated with a high morbidity and mortality. The diagnosis usually is made with transesophageal echocardiography, which is highly sensitive and specific for the disease. We present a case of suspected aortic root abscess 1 week after mechanical aortic valve replacement for native valve endocarditis. The diagnosis was made by the use of transesophageal echocardiography but surgical inspection revealed that the paravalvular fluid collection was excessive surgical adhesive. We discuss the clinical significance and differential diagnosis of aortic root abscess in the setting of infective endocarditis.
